COUPLER FOR WIFI 6 CHIP AND RADIO FREQUENCY SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/093358
Kind Code:
A1
Abstract:
The present utility model provides a coupler for a WiFi 6 chip and a radio frequency source device. The coupler for the WiFi 6 chip comprises a main signal line, a first coupling signal line, and a second coupling signal line; the main signal line is provided with a signal input port and a straight-through port; the first coupling signal line is provided with a first coupling port and a first isolation port; and the second coupling signal line is provided with a second coupling port and a second isolation port. The first coupling signal line and the main signal line are arranged at intervals and are coupled on a same layer; the second coupling signal line and the main signal line are arranged at intervals and are coupled on upper and lower layers; and the first coupling signal line and the second coupling signal line are arranged at intervals. In this way, when a coupling length is the same as that of a traditional design, the coupling degree is obviously improved, and the isolation degree is also good; and on the other hand, due to a special wiring design, the wiring length does not need to be very long, such that the layout is very facilitated. According to the present utility model, the overall wiring is simple, the coupling degree and the isolation degree are obviously improved, and the application range is wide.
